Investigation of Aggression Levels of University Students (Kocaeli University Case)

The aim of this study was to investigate the aggression levels of university students in different departments in terms of sport and other variables. The population of the study consists of university students studying at Kocaeli University; the sample group consists of a total of 700 students, 378 male and 322 female, studying in the Faculty of Sports Sciences, Faculty of Communication and Faculty of Education of Kocaeli University. A screening model was used in this survey. A Personal Information form developed by the investigator and a Turkish-adapted Buss-perry aggression scale was utilized to determine the aggressive attitudes of the individuals. The frequency distribution specified the demographic features and analyzed the data; the T-test examined the relationship between the two independent variables; Anova Variance was used to review the connections between more than one variable. Finally, the significance level is accepted as p<0.05. According to the findings of the research, there are statistically significant differences (p<0.05) in terms of gender, family structure, school department, family attitude, mother still living, sporting situation, kind of sport performed, reason for involvement in sport, cigarette-alcohol abuse and income level. We can state that sport positively affects the aggression levels of university students. Sport also varies by the gender variable, and males are more aggressive than females. It can also be pointed out that aggression varies by the school department, family attitude, cigarette-alcohol abuse, mother still living, reason for playing sport and income level

3rd grade students’ status of spending time with their families and implementation of values education in family in the turkish context

The purpose of this study was to determine how the primary school students spent their time with the parents and how their families spent their time with children and try to give the study group the value of giving importance to family unity through various activities. The study was carried out as action research. The participants of the research included 26 students, studying in Turkey. Before the action plan was formed, interviews were held with parents and students to determine how the students spend their time with the parents and how their families spent their time with the children. As a result of the analysis, an action plan was formed based on classroom activities and domestic activities. Within the framework of the action plan, case analysis, workshop, and family entertainment design were carried out. After the family entertainment, parents’ and students ' opinions about the activities were taken. As a result of the research, it was seen that students spent their time with their families at home non-interactively by watching television mostly. After the activities, the students and parents said that they were pleased with the activity and that the activity allowed them to spend time together

Rapid modelling of multi-stepped rotor dynamics

The major objective of the studies on the dynamic behaviour of rotors is to allow development of rotating machinery that will be free from vibrational problems. Rotor dynamics prediction has several important consequences for a large group of machinery. First of all, there are many machines with rotating components, i.e. rotors, such as turbines, compressors and pumps, machine tools, helicopters, dentist's tooth grinders etc. The dynamics of these systems are very critical for their proper functioning, stability, efficiency and health. For example, if one of the natural frequencies is in the operation region of the system, i.e. one of the excitation frequencies during the operation is close to one of the natural frequencies, then the system may resonate and the resulting large amplitude vibrations will cause loss of accuracy and efficiency in the operation, and may also damage the bearings and the rest of the machinery. There are two main approaches to rotor dynamics analysis. For existing rotors, the dynamics can be measured using experimental techniques such as modal analysis. Although this can be a fast approach, it requires the experimental set up be available. Also, if there are many different components added to the rotor, such as different tool holders and tools on a machine tool spindle, then the measurements must be repeated for each combination which may result in high number of tests and waste of productive time on the machine. Prediction of the rotor dynamics during the design is another critical case where dynamics analysis is required. Obviously, testing is not a possible technique for this case. FEA can be used for the prediction of the dynamics. This may be a viable solution in many cases, however the bearing contact parameters, i.e. stiffness and damping, must be known in order to develop the model. Also, many simulations have to be performed for optimal design resulting in highest dynamic rigidity with smallest possible rotary inertia. This is usually very time consuming, and the optimal configuration may never be obtained. The objective of this study is to develop a fast method for the dynamic analysis of rotor-bearing systems so that they can be used during the design and the operation of the machinery. The method can be used to determine the frequency response function of the system at critical locations for different geometric configurations very fast so that the design could be optimized. The effects and optimal values of some internal system parameters such as bearing preloads could also be determined using the method. Also, the dynamic response of the system could be updated after new components are added to the rotor

Karakterizacija emisije formaldehida i svojstava gorenja ekoloških kompozitnih ploča za graditeljstvo proizvedenih na bazi ljusaka kikirikija (Arachis hypogaea)

The building sectors are increasingly in need of more wood-based panels. Forests and environments are being destroyed to produce these wood-based panels. The aim of this study is to protect forest assets by recycling peanut (Arachis hypogaea) husk and manufacturing particleboard for green building design. The manufactured composite panels were subjected to combustion and formaldehyde tests. According to the test results, peanut husk reduced the combustion time and increased the combustion temperature. Phenol-formaldehyde adhesive decreased illuminance values and the peanut husk ratio increased the illuminance values. It was understood that, when the peanut husk additive ratio increased, combustion times decreased. Slow-combustion of green building composite panels delays the danger of collapse in case of a fire in a building. The combustion performance of the composite panels can be improved by adding non-combustible materials that do not affect the adhesion performance of the composite panels. When the adhesive type is taken into consideration, it is seen that the FF additive ratio reduces the combustion time. According to the formaldehyde emission test results, 24 hours after the manufacturing process all composite panels met the requirements of the board formaldehyde class E1. These composite panels can be used in green buildings as a sustainable building material. The furniture industry can also use these agro-fiber composite panels as green materials.Građevni sektor ima sve veću potrebu za pločama na bazi drva za čiju se proizvodnju uništavaju šume i okoliš. Cilj ovog istraživanja bio je zaštititi šumska dobra recikliranjem ljusaka kikirikija (Arachis hypogaea) i proizvodnjom iverica namijenjenih zelenoj gradnji. Na tako proizvedenim kompozitnim pločama provedena su ispitivanja gorenja i emisije formaldehida. Rezultati su pokazali da se dodavanjem ljusaka kikirikija smanjuje vrijeme gorenja i povećava temperatura izgaranja ploča. Fenol-formaldehidno ljepilo pridonosi smanjenju vrijednosti osvjetljenja, a uz veći udio dodanih ljusaka kikirikija povećava se razina osvjetljenja pri gorenju. Pretpostavljeno je da će se s povećanjem udjela ljusaka kikirikija smanjiti vrijeme gorenja. Sporo gorenje kompozitnih ploča namijenjenih zelenoj gradnji odgađa opasnost od urušavanja u slučaju požara u zgradi. Svojstva gorenja kompozitnih ploča mogu se poboljšati dodavanjem nezapaljivih materijala koji ne utječu na adheziju kompozitnih ploča. S obzirom na vrstu ljepila, ustanovljeno je da se s povećanjem udjela FF ljepila skraćuje vrijeme gorenja. Prema rezultatima ispitivanja emisije formaldehida 24 sata nakon procesa proizvodnje, sve su kompozitne ploče zadovoljile klasu emisije formaldehida E1. Zaključeno je da se ispitivane kompozitne ploče u zelenoj gradnji mogu upotrebljavati kao održivi građevni materijal. Kao ekološki prihvatljive, te se kompozitne ploče na bazi agrovlakana mogu primjenjivati i u industriji namještaja

ECONOMIC AND POLITICAL INTERACTION OF 2001 CRISIS: IMPLICATIONS FOR 2008 RECESSION?

As it is known, Turkey experienced a severe economic crisis in the year 2001. This economic crisis has been costly for the Turkish economy and has typically been accompanied by a collapse of output and employment as well as striking declines in real wages. Not only economic insufficiencies and bottlenecks but also political uncertainty had sizeable impacts in the formation of economic crisis. The 2001 Crisis interestingly caused a set of catastrophe and it is worthy to analyze its emergence, mal-administration, and wide damage on the Turkish economy and to show the structure that transformed political climate in the post-crisis period. The interaction of political and economic dimensions of 2001 crisis also accompanies strong implications for 2008 recession and this paper finally discusses lessons of 2001 crisis for 2008 recession through the lenses of interplay between politics and economics

Can SMEs in developing countries resist crisis? An analysis on Turkish and Albanian cases

SMEs have an important role in terms of their economic share in developedand developing economies, though there are different definitions of SMEamong various organizations and countries. Today, instead of giantindustries, SMEs having gained importance in the developing economies,become advantageous being economic enterprises having the capability ofquick adjudication, working with less capital but more intense labor andhaving low cost of management and thus having cheap production. In short,the concept of small is beautiful becomes important in the current economic conjuncture with giant firms.In this context, SME definition and SME's role in Turkish and Albanianeconomies will be dealt with. It will be also questioned whether SMEs indeveloping countries resist crisis or not
